Tran 1, Excise credit on Vat invoice

1. Value of the closing stock. i.e., Invoice amount without VAT. (assuming VAT credit is taken and VAT is not included in stock price)

2. Value of excise duty for which credit is not taken, but mentioned in the invoice. 

3. 7A 

100% credit of excise duty can be taken as per sec.140(3)

No. As per PDF form available in CBEC website, 7B is a part of 7(a). But if you look at the online tran-1, there is no 7A or 7B. It is only 7(a).

What you are refering is actually 7(b).
